Copper Toxicity and Extracellular Release in \u3ci\u3eSelenastrum Capricornutum\u3c/i\u3e

Copper toxicity was investigated using the green alga, Selenastrum capricornutum. Two major areas were investigated: the forms of copper which are toxic to growth of the alga and factors that can change the concentration of free copper, Cu2+(aq), in the growth medium during the logarithmic growth of the organism. This research has shown that S. capricornutum is sensitive to the free Copper ion, Cu2+(aq), irrespective of the total copper concentration
